Abstract

A hot melt file envelope includes a prefabricated envelope, a U-shaped groove and a hot melt adhesive. The U-shaped groove is an aluminum alloy U-shaped groove or other plasticity deformed U-shaped groove. A ridge sealed part of the prefabricated envelope is arranged on the bottom of the plasticity deformed U-shaped groove. The inner lateral of the ridge sealed part of the prefabricated envelope is coated with the hot melt adhesive. The outer lateral of the ridge sealed part of the prefabricated envelope is pasted to the inner lateral groove bottom of the plasticity deformed U-shaped groove. Two lateral walls of the plasticity deformed U-shaped groove are equipped with parallel grooves. The utility model provides the hot melt file envelope, which has the advantages of firm bind, convenience, rapid performance, simple structure, good appearance effect and easy storage.

Description

A kind of hot melten type file big envelope

Technical field

The utility model relates to cultural goods, specifically a kind of text bookbinding file big envelope.

Background technology

In the prior art, text bookbinding great majority adopt devices such as stapler, loose-leaf binder, cushion rubber bookbinding, hot melten type bookbinding and perforation binding, and these devices are in the defective of the equal various degrees in aspect such as aesthetic property, reliability and operating efficiency.

Summary of the invention

The purpose of this utility model is intended to overcome above-mentioned the deficiencies in the prior art, propose a kind of bind firm, convenient and swift, simple in structure, appearance is good and the hot melten type file big envelope that is easy to deposit.

Realize the technical scheme of above-mentioned purpose: a kind of hot melten type file big envelope, comprise prefabricated big envelope, U type groove and PUR, U type groove is the U type groove of plastically deformable, and the envelope ridge of prefabricated big envelope is disposed in the U of plastically deformable type groove bottom land, and the inboard at the envelope ridge place of prefabricated big envelope is coated with PUR.

The outside at the envelope ridge place of prefabricated big envelope is bonded at the bottom of the inner side slot of U type groove of plastically deformable.

The two side of the U type groove of plastically deformable has parallel groove.

The U type groove of plastically deformable is the aluminium alloy U-lag.

Adopt technique scheme, its beneficial technical effects is: 1, tool PUR metal ridge extruding bonding and plastically deformable simultaneously clamps function, thereby bookbinding firmly.2, have parallel groove, the distortion when being convenient to clamp in the two side of the U of plastically deformable type groove.3, simple in structure, both be convenient to produce, operate and convenient and swift, be applicable to all kinds of literary composition page or leaf bookbinding of office, be comparatively desirable office appliance.4, because the utility model is simple in structure regular, be easy to deposit.In sum, the utility model is a kind of simple in structure, result of use good, practicality is stronger hot melten type file big envelope.

Description of drawings

Fig. 1 is a kind of structure (analysing and observe) figure of hot melten type file big envelope.

Fig. 2 is the side view of Fig. 1.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Embodiment: see figures.1.and.2, a kind of hot melten type file big envelope, the U type groove 2 and the PUR 3 that comprise prefabricated big envelope 1, plastically deformable, the U type groove 2 of plastically deformable is the aluminium alloy U-lag, the two side of the U type groove 2 of plastically deformable has parallel groove 4, crimp when being convenient to clamp, the envelope ridge of prefabricated big envelope 1 is disposed in the bottom land of the U of plastically deformable type groove 2, the inboard at the envelope ridge place of prefabricated big envelope 1 is coated with PUR 3, and the outside at the envelope ridge place of prefabricated big envelope 1 is bonded at the bottom of the inner side slot of U type groove 2 of plastically deformable.

During use, the literary composition page or leaf that will be in sheets is placed in the prefabricated big envelope 1 and integral body places the hot melt binding machine, in binder, make PUR 3 fusings and bonding with the literary composition page or leaf by heating to aluminum alloy trough 2, the clamp mechanism of binder is pushed the both sides of aluminum alloy trough 2 subsequently, so that alloy groove 2 clamps the literary composition page or leaf, reach the purpose of reliable bookbinding.

Must be pointed out that it is a special case that the U type metallic channel of present embodiment plastically deformable adopts the aluminium alloy U-lag, also can adopt the U type metallic channel of other plastically deformable, as long as by being out of shape after the extruding and clamping civilian page that is bound.In like manner, the quantity of the parallel groove that U type groove two side is offered can be decided as required, and one, two or more parallel groove can respectively be offered in the two side.

Claims

1, a kind of hot melten type file big envelope, comprise prefabricated big envelope, U type groove and PUR, it is characterized in that: U type groove is the U type groove of plastically deformable, and the envelope ridge of prefabricated big envelope is disposed in the U of plastically deformable type groove bottom land, and the inboard at the envelope ridge place of prefabricated big envelope is coated with PUR.
